使用“knit html”后，内联代码不会突出显示。函数 [英] Inline codes are not highlighted after using "knit html" function in Rstudio

问题描述

我写了一个带有`引用的内联代码的 .Rmd 文件，我使用 knit html 函数将 .Rmd 文件转换为 .html 。但是，内联代码未突出显示为 stackoverflow ，我查看了 .html 文件的源代码，发现设置为

I wrote an .Rmd file with some inline codes quoted by "`", and I used the knit html function in Rstudio to convert the .Rmd file to .html. However, the inline codes were not highlighted as on stackoverflow, and I took a look at the source codes of the .html file and found that the setting was like

tt, code, pre {
font-family: 'DejaVu Sans Mono', 'Droid Sans Mono', 'Lucida Console', Consolas, Monaco, monospace;
}

我试图改变这个区块：

tt, code, pre {
font-family: 'DejaVu Sans Mono', 'Droid Sans Mono', 'Lucida Console', Consolas, Monaco, monospace;
background-color: #F8F8F8;
}

但是，我不想在每次编写 .Rmd 文件到 .html 。我已经阅读R中的 knit2html 和 markdownHTMLOptions 的帮助文件，但没有找到解决方案。

However, I do not want to do such work every time after I knit the .Rmd file to .html. I have read the help files of knit2html and markdownHTMLOptions in R but found no solution. Is there any solution to this issue?

推荐答案

使用最新版本的 markdown package on CRAN，您可以使用头参数向HTML输出中添加其他CSS代码，例如

With the latest version of the markdown package on CRAN, you can use the header argument to add additional CSS code to the HTML output, e.g.

library(knitr)
knit2html(...,
  header = c('<style type="text/css">', 'code{background-color: #F8F8F8;}', '</style>'))

只需将它设置为〜/ .Rprofile 中的全局选项即可：

Or just set this as a global option in your ~/.Rprofile:

options(markdown.HTML.header = c('<style type="text/css">', 'code{background-color: #F8F8F8;}', '</style>'))

并且 markdown 您只需运行 knit2html（），而无需明确指定头参数

And the markdown package will use it every time when you simply run knit2html() without explicitly specifying the header argument.

对于RStudio，它有点棘手。请参阅文档自定义Markdown呈现。

With RStudio, it is a little trickier. See the documentation Customizing Markdown Rendering.
